PLOW.

SPECIFICATION forming part of Letters Patent No. 441,891, dated December 2, 1890.

Application filed July 1'7, 1890.

To aZZ whom it may concern:

Be it known that I, JOHN PEHRSON, a citizen of the United States, residing at Rockford, in the county of \Vinnebago and State of Illinois, have invented certain new and useful Improvements in Ilows, of which the following is a specification.

My improvement relates to that class of plows commonly known as sulky-plows; and it consists of certain new and useful features of construction and combinations of parts hereinafter described, and specifically pointed out in the claims.

Referring to the accompanying drawings, which form a part of this specification, Figure 1 is a right side elevation of a plow embodying my invention. Fig. 2 is a top plan view of the same. Fig. 3 is a verticalsection at the dotted line 3 3 in Fig. 2 of parts there shown. Fig. 4 is a Vertical partial section at the dotted line 4 4 in Fig. 2 of parts there shown. Fig. 5 is a vertical partial section at the dotted line 5 5 in Fig. 2 of parts there shown. Figs. 0 and 7 are isometrical rightside views in detail of parts for connecting the yoke of the caster-wheel of the plow with the beam thereof. Fig. 8 is a left side elevation of the same operatively connected together and connecting the caster-wheel yoke with the plow-beam.

Like letters of reference indicate corresponding parts throughout the several views.

A is the main frame of the front portion of the plow.

A A are axles pivotally mounted therein and having wheels A mounted thereon.

B is a Y-shaped tongue support, the bifurcations B B whereof curve downward and backward and have pivotal connection at their lower ends with the axle A.

B is a tongue pivotal] y connected with the portion B of the tongue-support B.

O is a segment-plate fast to the reduced rear end of the tongue B and having a detent-slot C in the center of the peripheral portion thereof.

C is a detent mounted on the part B and adapted to engage with and be disengaged from the slot C in the segment-plate O.

C is a curved foot-lever pivotallymounted on the bolt 0 G is a rod or other suitable connection be- Serial No. 359,054. (No model.)

tween the short arm ()of the levcrC and the .detent C (1 is an actuating-spring, which holds the detent C into engagement with the slot 0 in the plate 0 at all times, except when it is withdrawn therefrom by pressing on thelever C \Vhen the plow is in use, the lever C plays up and down, participating in all the vertical motions of the tongue B and when the plow is unused and the free end of its tongue rests on the ground the detent C will still be held into engagement with the plate 0, thereby at all times preventing the tongue from turning on its pivot, except when the operator so desires and presses on the lever to allow it to do so. The tongue B maybe swung on its pivot either to the right or the left about thirty degrees, as indicated by dotted lines in Fig. 2, preparatory to making a right or left turn in plowing. If it should be desirable or necessary to change the center of draft of the plow, the detent C may be located at Y and the tongue B repivoted to the part B accordingly and the rod 0 connected with the hole 0 in the part 0.

D is a plow beam connected with the part A.

D D are the mold-board and landside of the plow.

E is a bearing-bracket rigidly connected with the plow-beam D.

E is a caster-wheel-yoke-stem bearing mounted on the bearing E on the bracket E and provided with the downwardly-extending arm E and horizontal lug E.

E is a caster-wheel-yoke stem inserted through the bearing E, wherein it may be rotated.

E" is a caster-wheel yoke fast to the lower end of the stem E.

E is a caster-wheel mounted in the yoke E F is a collar fast to the upper end of the stem E and provided with the parallel horizontal lugs F F having holes F F therein concentric with each other and the hole E in the lug E F is a detent adapted to slide in the holes F E E F is a pedal fast to the upper end thereof.

F is a spring for holding the detent F out of engagement with the lug E.

G is an adjusting-lever pivotally mounted on the bolt G at G G3 is a connecting-bar pivot jointed to the lower ends of the lever G and the arm E.

H is a segment-rack fast to the beam D and bracket E. 7 5 Pressing the lever G downward raises the heel of the plow, andthereby throws its point downward into the ground.

VVhenever it is desired to dispense with the caster-wheel E it may be raised to and sus- [O pended in the position indicated by the dotted lines in Fig. 2 by carrying the lever G upward.

It will frequently be found to be convenient and often necessary to prevent the casterwheel E from turning on its swivel-joint when backing up and backing out of a furrow with the plow for any purpose. In order to do this, it is only necessary for the operator to press the pedal F When the detent F will descend and engage with the part E thereby rigidly connecting the parts E F while such connection continues.

I claim 1. In a plow, in combination, the plow-beam, 2 5 the bearingbracket rigidly connected therewith, the caster-W11eel-yoke-stem bearing pivotally mounted on the bearing-bracket and provided with the downwardly-extending arm E the caster wheel yoke stein inserted through and revoluble in the caster-wheelyoke-stem bearing, the caster-wheel yoke fast to the lower end of said stem, the adjustinglever mounted on the bearing-bracket, and the connecting-bar pivot jointed to the lower ends of the adj usting-lever and arm E substantially as and for the purpose specified.

2., In a plow, in combination the plow-beam, the bearing-bracket rigidly connected therewith, the caster-wheel-yoke-stern bearing pivotally mounted on said bracket and provided with the downwardly-extending arm E and the lug E having a vertical hole therein, the caster-wheel-yoke stem inserted through and revoluble in said bearing, the collar fast to the upper end of said stem and provided with the lugs F F having holes therein concentric with each other and the hole in the lug E the detent adapted to slidein the holes in said lugs, the pedal fast to the upper end of said detent, the spring for holding said detent out of engagement with the lug E the casterwheel yoke fast to the lower ends of said stem, and the caster-wheel mounted in the yoke, substantially as and for the purpose specified.
